Dataset of bond strength and failure mode between FRP bars and UHPC or UHPSSC

In order to investigate the bond strength and failure mode between fibre-reinforced polymer (FRP) bars and ultra-high-performance concrete (UHPC) & ultra-high-performance seawater sea sand concrete (UHPSSC) effectively, 542 experimental data acquired from pullout tests were collected from relevant research papers. The failure modes consist of pullout failure and concrete splitting failure. 14 input parameters (Vf of steel fibre, Vf of PP/PE fibre, Concrete type, Concrete compressive strength, Water-to-binder ratio, Sand-to-binder ratio, Bar diameter, Cover-to-diameter ratio, Bonded-length-to-diameter ratio, Rib-spacing-to-diameter ratio, Rib-height-to-diameter ratio, Bar surface treatment, Bar fibre type, Bar tensile elastic modulus) were selected to study the effects of mechanical property and composition of UHPC/UHPSSC, along with the mechanical, geometric, and surface properties of FRP bar on bond strength and failure mode. The developed dataset can serve as an effective resource for investigating the bond strength and failure mode between FRP bars and UHPC/UHPSSC.为有效探究纤维增强聚合物（fibre-reinforced polymer, FRP）筋与超高性能混凝土（ultra-high-performance concrete, UHPC）及超高性能海水海砂混凝土（ultra-high-performance seawater sea sand concrete, UHPSSC）之间的粘结强度与破坏模式，研究人员从相关学术论文中收集了542组拉拔试验所得的试验数据。试验破坏模式分为拉拔破坏与混凝土劈裂破坏两类。本研究选取14项输入参数，包括钢纤维体积掺量、PP/PE纤维体积掺量、混凝土类型、混凝土抗压强度、水胶比、砂胶比、筋材直径、保护层厚度与筋径比、粘结长度与筋径比、肋间距与筋径比、肋高度与筋径比、筋材表面处理方式、筋材纤维类型、筋材拉伸弹性模量，用以分析UHPC/UHPSSC的力学性能与组成成分，以及FRP筋材的力学、几何与表面特性对粘结强度及破坏模式的影响。所构建的数据集可作为探究FRP筋与UHPC/UHPSSC之间粘结强度与破坏模式的有效研究资源。
